Across the Northeast United States Tuesday, preparations were underway for an impending winter storm. Winter storm Quinn was expected to hit Wednesday, bringing with it heavy snow, rain and high winds.

The National Weather Service issued winter storm warnings in a number of states, including Connecticut, New York, New Jersey and Pennsylvania. Schools began announcing closures Tuesday afternoon in preparation for the storm.

While not all schools had yet announced their closures, Philadelphia said all public and Parochial schools would be closed due Wednesday to inclement weather, KYW-TV reported.

Worcester Public Schools in Massachusetts also announced there would be no school and no before and after school activities. Most schools in New Jersey, where a state of emergency was declared by Governor Phil Murphy, were also closed in preparation for the nor’easter.

Many schools said they’d determine whether there would be classes Thursday on Wednesday night.

The city of Philadelphia also announced all its municipal offices would be closed Wednesday as a result of the weather. In Pennsylvania, Governor Tom Wolf said certain types of vehicles would be banned from roadways as winter storm Quinn bore down, The Weather Channel reported.

The Massachusetts Department of Transportation also asked people not to drive during the storm, citing “hazardous travel conditions.” In New York City, the Emergency Management Department issued a hazardous travel advisory for Wednesday as well.

“Mother nature’s March Madness continues as another nor’easter is forecast to bring snow that will make travel dangerous on Wednesday,” Emergency Management Commissioner Joseph Esposito said in a statement Tuesday. “New Yorkers should take mass transit if possible and allow for extra time.”

Winter storm Quinn comes on the heels of winter storm Riley, which wrought havoc in parts of the Northeast, knocking out power and plowing through seawalls. It remained unclear whether Quinn would pack the same punch as Riley, though authorities warned residents to be prepared no matter what.
